Abstract
The present invention relates to a firmware updating method for updating a plurality of electronic devices. Firstly, providing a firmware updating file with a plurality of firmware program codes, and describing the firmware program codes to respectively correspond to the electronic devices; then, decompressing a part of the firmware updating file and writing the electronic device; thirdly, checking whether the electronic device has write errors or not; finally, checking whether updating is finished or not, if not, repeating write steps.
Description
Technical field
The present invention relates to a kind of update method, and be particularly related to a kind of update method of firmware.
Background technology
Because the speed of electronic product progress is very fast, often product arrive the user on hand after, need add new function again, or find some mistake.Generally be to right a wrong or increase new function in the mode of upgrading firmware.
In the process of firmware update, firmware update execute file and firmware program code (firmwarecode) need be arranged.The firmware update execute file is to carry out in operating system, and operating system for example is Windows, DOS or Linux, firmware program code is write the flash memory in the electronic product.
Yet, in the general firmware update process, once only can upgrade with regard to an electronic product, in the time of therefore need upgrading as if the electronic product that several different models are arranged, the time that needs cost to upgrade for several times.
In addition, the firmware of recent electronic product is also more and more big, for example is the DVD CD writers, and therefore its firmware program code can't be upgraded under dos operating system promptly greater than 1M bits.
Summary of the invention
In view of this, purpose of the present invention is exactly to carry out providing under a kind of operating system in memory-limited, and can once upgrade the firmware update of multinomial electronic product.
According to purpose of the present invention, a kind of firmware update is proposed, in order to upgrade a plurality of electronic installations.At first, provide a firmware update file with a plurality of firmware program code, these a little firmware program code are the so far a little electronic installations of correspondence respectively.Then, the part of decompression firmware update file, and write corresponding electronic installation.Then, check whether write error is arranged.At last, check whether to upgrade to finish, if not, then repeat write step.
According to another object of the present invention, a kind of firmware update documenting method is proposed.At first, provide a plurality of firmware program code.Then, import a Release parameter and a model parameter of each firmware program file, and confirm.At last, whether decision will be compressed these firmware program code, and produce the firmware update file according to this.
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below.

Embodiment
Please refer to Fig. 1, it shows a kind of firmware update documenting method flow diagram according to a preferred embodiment of the present invention.Method for making in the present embodiment is to make automatically with a program to comprise the updating file of a plurality of firmware program code, so that upgrade a plurality of electronic installations at the same time, for example is DVD ROM, DVD CD writers, motherboard or the like.At first, shown in step 10, receive a plurality of firmware program code, the user can import a plurality of firmware program code in this program.Then, shown in step 12, confirm the parameter such as manufacturer, model of the version of each firmware program code and pairing electronic installation.Because the different employed firmware program code of electronic installation is inequality, therefore when making this updating file, need be confirmed the electronic installation that firmware program code is suitable for, so that when upgrading backward, avoid being updated to wrong version or wrong model.
Then, shown in step 14, whether decision will be with these firmware program code compression.The benefit of compression is that one side can be carried out under the DOS environment, can make updating file can hold more kinds of firmware program code on the other hand.Under the DOS environment, have only the internal memory of 640Kbytes to use, still the firmware of general DVD CD writers is promptly greater than 1Mbytes, and therefore the words of not compressing can't be used under the DOS environment.Therefore the user can be according to the operating system of carrying out when upgrading, or the number of required firmware program code and do the consideration of whether compressing.In the present embodiment, therefore half when not compressing of the firmware program code after the compression can hold more firmware program code.
At last, shown in step 16, produce the updating file that comprises above-mentioned firmware program code.This updating file is can more comprise or do not comprise the renewal execute file, looks closely user's consideration and decides.
After generation comprises the updating file of a plurality of firmware program code, can begin to upgrade according to this firmware of electronic product.Fig. 2 shows a kind of firmware update process flow diagram according to embodiments of the invention.At first, whether shown in step 20, checking needs the firmware program code in this updating file is decompressed, check just whether this updating file compresses firmware program code in manufacturing process.If need to decompress, then execution in step 21, otherwise execution in step 25.
In step 21, the firmware program code in the decompression updating file.This action that decompresses is to separate some earlier, or a complete solution: for example may only separate some earlier under the DOS environment.Then, in step 22, the data that step 21 decompressed are write corresponding electronic installation.More can check the version of firmware program code and the firmware version in the electronic installation in this step, and check that whether firmware program code is consistent with corresponding electronic installation.
Then, whether in step 23, checking has write error.In this step is that the data that will write in step 22 read out, and is compared, to confirm whether to be written to merit.If write error is arranged, then get back to writing again after step 21 decompresses this partial data again, or getting back to step 22 writes again.Then in step 24, check to upgrade whether finish.Do not finish if upgrade as yet, then get back to step 21 and continue the decompression firmware program code.Renewal is a method ends after finishing.
Under the situation of the firmware program code that need not decompress, execution in step 25 directly writes the firmware program code in the updating file corresponding electronic product.Be the mode that to use multithreading (multi-thread) in the step 25, simultaneously a plurality of firmware program code write corresponding electronic product respectively.Then, whether in step 26, checking has write error.If have, then get back to step 25 firmware program code of mistake is write again, otherwise method ends.
Fig. 3 is a computer system synoptic diagram of using the method for present embodiment.Computer system 300 comprises main frame 320 and many CD-ROM drives 310,312,314 and 316.If these CD-ROM drives 310-316 is different model, and need carry out firmware update, utilize the method for present embodiment can once upgrade the firmware of all CD-ROM drives, saving manual operation and valuable time.For example be the production division of computer maintenance department or electronic installation, utilize the method for present embodiment can promote work efficiency and then reduce cost.
The disclosed firmware update of the above embodiment of the present invention can once upgrade many electronic installations, saves manual operation and time, and can carry out under the interior operating system that has a limitation.
In sum; though the present invention discloses as above with a preferred embodiment; right its is not in order to limit the present invention; anyly have the knack of this skill person; without departing from the spirit and scope of the present invention; when can being used for a variety of modifications and variations, so protection scope of the present invention is as the criterion when looking the accompanying Claim book person of defining.
